After age 60, presbyopic changes in near vision should
stop and prescription changes should occur less frequently. Nevertheless,
the chance of Cataracts, Glucoma and other age related eye diseases
is getting higher. Macular degeneration is primarily age related,
affecting one in seven people over the age of 50, in Australia.

Age-related macular degeneration
If straight lines appear distorted or wavy or there appears to be
a blind spot or empty area in the centre of your vision, you may
have signs of (AMD). The disease affects the macula, the part of
your retina that is responsible for central vision where the eye's
acuity is sharpest. Although central vision may be seriously impaired
by macular degeneration, side vision is not affected.

The majority of people with macular degeneration cannot expect to
regain normal vision. Prompt treatments may be successful in retarding
vision loss in some cases. Low vision magnifying aids, large print
books, television readers, and better lighting can help may individuals
continue to read and perform some visual tasks. Before aids are
prescribed, a comprehensive medical eye examination should be performed
to determine if the impairment of sight is medically treatable.
